Abstract

L'invention concerne un système d'entraînement laser à l'arme à feu. Ce système comprend un ensemble émetteur laser et un ensemble adaptateur de cartouche et utilise des cartouches à blanc modifiées de manière à simuler le fonctionnement d'une arme à feu. Les cartouches à blanc modifiées contiennent chacune une substance explosive en quantité juste suffisante pour tirer-réenclencher l'arme à feu. L'ensemble laser est conçu pour se fixer à un canon et à un guidon d'arme à feu et il émet un faisceau de lumière laser en direction d'une cible de système d'entraînement lorsque la détente de l'arme est actionnée. Le faisceau laser présente généralement la forme d'une impulsion présentant une durée suffisante pour que la cible du système détecte le point d'impact du faisceau. L'ensemble cartouche est placé à l'intérieur du canon de manière à adapter l'arme à feu pour qu'elle soit compatible avec des cartouches à blanc afin de simuler le fonctionnement d'une arme à feu.
